Nonuniform Sampling of Periodic Bandlimited Signals
Abstract--Digital processing techniques are based on representing a continuous-time signal by a discrete set of samples. This paper treats the problem of reconstructing a periodic ...

Fast convolution and Fast Fourier Transform under interval and fuzzy uncertainty
Convolution y(t) = a(t − s) · x(s) ds is one of the main techniques in digital signal processing. A straightforward computation of the convolution y(t) requires O(n2) steps, wh...

Slack redistribution for graceful degradation under voltage overscaling
Modern digital IC designs have a critical operating point, or "wall of slack", that limits voltage scaling. Even with an errortolerance mechanism, scaling voltage below a...

Self-Timed SRAM for Energy Harvesting Systems
Abstract. Portable digital systems tend to be not just low power but power efficient as they are powered by low batteries or energy harvesters. Energy harvesting systems tend to pr...
